Implementations

impl Gas

pub fn new(gas_file: &str) -> Gas

Creates a Gas object from a file .json file

pub fn TP<'a>(&'a mut self, temp: f64, press: f64) -> &'a mut Self

Set temperature and pressure. Thermo properties are recalculated

Examples

let temp = 350;
let press = 2e5;
gas.TP(temp, press);
assert_eq!(350, gas.T());
assert_eq!(2e5, gas.P());

pub fn TPX<'a>(
    &'a mut self,
    temp: f64,
    press: f64,
    mol_frac: &str
) -> &'a mut Self

Set temperature, pressure, and mole fraction of species. Thermo properties are recalculated

Examples

let temp = 350;
let press = 2e5;
let mole_frac = "O2:0.21, N2:0.79";
gas.TPX(temp, press, mol_frac);
assert_eq!(350, gas.T());
assert_eq!(2e5, gas.P());
assert_eq!(0.21, gas.mol_frac_of("O2"));

pub fn X<'a>(&'a mut self, mole_frac: &str) -> &'a mut Self

Set mole fraction of species from &str. Thermo properties are recalculated

Examples

let mole_frac = "O2:0.21, N2:0.79";
gas.X(mol_frac);
assert_eq!(0.21, gas.mol_frac_of("O2"));
assert_eq!(0.79, gas.mol_frac_of("N2"));

pub fn X_array<'a>(&'a mut self, mol_frac: &Array1<f64>) -> &'a mut Self

Set mole fraction of species from ndarray::Array1, must be the same size. Thermo properties are recalculated

pub fn TPX_array<'a>(
    &'a mut self,
    temp: f64,
    press: f64,
    mol_frac: &Array1<f64>
) -> &'a mut Self

pub fn if_mixed_with(&self, mass: f64, add_gas: Vec<(f64, &str)>) -> Array1<f64>

Returns the equivalent mole fraction, if a mass, in kg, of self were mixed with other gases in add_gas<(mass, composition)>

Examples

gas.X("O2:1.0");
let additional_gas = vec![(0.329337487, "N2:1.0")];
let mix_mole_frac: Array1<f64> = gas.if_mixed_with(0.100, additional_gas);
//mix_mole_frac has: O2:0.21, N2:0.79
